Coroutine - events not working

Question

I have spent endless nights, pulling my hair out a burning out my brain, why? Because I cannot seem to wrap my head round why my code will not work.

I am using a coroutine to enable an event to work.

I want a loading screen (a scene) to wait 5 seconds when it starts and to wait for the space bar to be pressed to actually load the next level... Please help me, I cannot stand my pain.

 function start() 
 {
 
 yield WaitForSeconds (5);
 gameObject.Find("Continue").renderer.enabled = true;
 gameObject.Find("Continue").renderer.material.color = Color.gray;
 StartCoroutine("Do");
 
 
 function Do(){
 if
 
       (Input.GetKeyDown(KeyCode.Space))
       {
       
 Application.LoadLevel("OpeningTutorialScene");
 
 
 }
 }

This is what you need:

 function Start()
 {
     yield WaitForSeconds (5);
     var renderer = gameObject.Find("Continue").renderer;
     renderer.enabled = true;
     renderer.material.color = Color.gray;
     while(true)
     {
         if (Input.GetKeyDown(KeyCode.Space))
         {
             Application.LoadLevel("OpeningTutorialScene");
         }
         yield;
     }
 }

btw: note that "Start" starts with a capital "S" or it won't work. "start" and "Start" is not the same thing.

Oops, just added code in, now it is freezing my unity and application in dev build when the 5 secs are over?

Coroutines are tricky business sometimes. Try this method instead.

 private var startTime : int = 0;
 public var waitForSecondsTime : int = 0;
 
         function Awake() 
         {
             startTime = Time.time;
             gameObject.Find("Continue").renderer.enabled = true;
             gameObject.Find("Continue").renderer.material.color = Color.gray;
         }
          
         function Update ()
         {
           if (Time.time > startTime + waitForSecondsTime)
           {
              Do();
           }
         }
 
  
         function Do()
         {
            if (Input.GetKeyDown(KeyCode.Space))
            {
               Application.LoadLevel("OpeningTutorialScene");
            }
         }
